A still urtherobject of the inventionV is to provide'a device of thecharacter described that will be strong, durable, efficient, and simpleand comparatively inexpensive to construct, also one in which theseveral parts will notA belikely to' get out-.ofv working order.

With .the above and other objects in Yview l the invention hasrelation'to certain novel features of construction andfoperation, anvexample of which is described in the .fol- -lowing specication andillustrated in the s accompanying drawings, wherein;

pump cylinders'are of suitableconstruction and are connected by pipes 19with check valves 20 mounted on the ends of a T -head 21 carried on afluid tank 22' secured on the tongue l.' The tank is adapted to have inftroduced therein a suitable spraying fluid by removing a cap v23. Thepumps force air :into the tank Wherebythe uid 4is placed under.pressure.

- The inventionl is contemplated as a cultivator attachment andy where'tubular gangs are present these are utilized as' conductors for theiuid, but where solidgangs are env- Aa5 I on the frame, an aircompressor plant mounted on the frame and having operative connectionwith one of the ground wheels, an air line connection between the saidplant andthe tank, a fluid conveying connection extending from the tankand including a flexible element, and a nozzle mounted at the rear endofone of the gangs, the gang having provision for conveying the fluid fromthe conveying connection to the nozzle.

2. The combination with the frame, ground wheels and gangs of acultivator; of a spraying attachment comprising, a fluid tank mounted onthe frame, an air compressor plant mounted on the frame and havingoperative connection with one of the wheels of the cultivator, an airline connection between the plant and the tank, a fluid conveyingconnection leading :from the tank and including a flexible element, anda nozzle mounted on the rear end of one of the gangs -and having fluidconnection with the conveying connection.

3. vThe combination with the frame, ground Wheels and the tubular gangsof a cultivator; of a spraying attachment comprising, a fluid tankmounted on the frame, an air compressor plant mounted on the frame anddriven by one of the groundwheels, an air pipe leading from the plant tothe tank and including a check valve, a distributing pipe extending fromthe tank and directed downward, a flexible pipe secured to thedistributing pipe, an elbw coupled with the exible pipe, said elbowbeing attached to forward end of one of the tubular gangs, and aninwardly directed nozzle mounted on the rear end of said gang.

In testimony whereof I affix my signature.
